As Life & Style exclusively reported, Jennifer Lopez and Alex Rodriguez secretly got engaged during their recent trip to Paris — and her kids, nine-year-old twins Max and Emme, couldn’t be more excited!

A source tells Life & Style that the duo, whose dad is J.Lo’s ex-hubby Marc Anthony, has become fast friends with A-Rod’s daughters, Natasha, 12, and Ella, 9. “J.Lo can’t wait for them all to be one big, happy family,” the source shares. “This is a real dream come true for her.”

The brunette beauty showed just how close the two families have become in a series of photos taken poolside. In one pic, Max sits on Alex’s stomach while Emme laughs in the background.

Though the singer and the former MLB star have only been dating for a few months, it didn’t take long for things to get super serious between the couple. “She’s crazy about A-Rod and loves everything about him,” the source says of J.Lo, while Alex “believes she is the love of his life.”

That’s why no one’s surprised by A-Rod’s romantic Parisian proposal, which took place in their presidential suite at the Le Meurice hotel. “He got down on one knee and asked J.Lo to marry him. [She] burst into tears and said yes!” the source reveals.

Jen previously revealed how the duo ended up together after having known each other for years. “It’s very simple. I was having lunch somewhere and I saw him. He passed by,” the Shades of Blue actress explained on The Ellen DeGeneres Show. “Afterwards I went outside, but for some reason I felt like tapping him on the shoulder and said, ‘Hi.'”

A-Rod ended up texting her later on, even though the two never exchanged info. Sneaky little devil!
